Title: Throttle valve control device for internal combustion engine
Inventor: ENDO TETSUO
IPC: F02D45/00
Filed: 1994-03-29
Abstract: PURPOSE:To enable learning of full close position during vehicle traveling even when the learning of full close position is not performed before starting, by learning the full close position when a control valve is controlled to a specified opening degree or less, in the case where an engine is started before the learning of full close position and drive control of the control valve is started. CONSTITUTION:When a vehicle is operated, first, input voltage or the like in a throttle position sensor 11 and a control unit 4 is taken in and a target opening degree signal 5 and a throttle opening degree signal 12 are compared with each other to judge whether or not a motor 6 is controllable. In the case of controllable, motor control is conducted and full close position learning is conducted if the vehicle is stopping. However, in the case where traveling is started immediately after key-ON and the full close position learning is not conducted, possibility of the full close position learning is judged based on the target opening degree signal, and if the learning is possible, the full close position learning is conducted. Feedback control computation is performed based on a throttle opening degree detection value and the target opening degree value so as to determine a drive voltage of the motor 6.

Abstract: PURPOSE:To enable combersome operations to be eliminated by providing a carrying control means so as to allow the feeding to be automatically switched over to a paper feeding means after the feeding of the recording medium from an intermediate paper feeding/discharging means, has been finished. CONSTITUTION:When a printer receives information on a picture image from an outside device 5, data for the required mode selection is determined by a carrying control means 6, then a paper feed command is directed to a paper feeding means 1 so as to feed recording paper of the required size from either one of paper feeding sections. Subsequently, the picture image is formed in order at a picture image forming section based on the data for the picture image received on the recording paper which is fed accordingly at regular time intervals. After the recording paper for forming the picture image on its both sides, has been finished in discharging from an intermediate paper feeding/discharging means 3, the carrying control means 6 allows the feeding to be automatically switched over to the paper feeding means 1. If the feeding from the means 3 has been selected when jamming is detected by a carrying condition detecting means 4 and when power is put on, the feeding is allowed to be automatically switched over to the feeding means 1 with the previous selection released. This configuration enables controllability to be augmented.

Abstract: PURPOSE:To detect the exchange time of a filter easily, by detecting the difference of galvanic electromotive force of each part of the upper flow and lower flow on a water passage of water to be treated of a dechlorination filter. CONSTITUTION:The inner part of a cylindrical filter vessel 2 of a dechlorination apparatus 1 is divided into three filter rooms, that is, an upper part 7, a  middle part 8 and a lower part 9 and activated carbon 10 for removing chlorine  in raw water is packed as a filter material in each filter room. When city water containing chlorine is passed through the apparatus 1 as the raw water, an absorption band of chlorine by the carbon 10 is formed at an early stage of water flowing, but leakage of residual chlorine is nearly absent and the electromotive force of galvanic electrodes 8, 9 of the upper and lower flows are coincident with each other. When the flowing is continued, the difference of the electromotive force between both electrodes is generated accompanied with movement of the adsorption band of chlorine. When the flowing is continued moreover, said band is reached to the room 9 and the electromotive force between both electrodes are coincident with each other again. It is decided that the filter attained to that point of time becomes an exchange time.
